Subscription-based streaming services are favored ahead of users' existing media libraries.
Two weeks ahead of the PlayStation 4's November 15 debut, the brand's official blog stepped up to answer some frequently asked questions -- and refuted some basic assumptions about the entertainment system's remit.
Support for MP3 music files, external hard drives, CDs, and Sony's DLNA home streaming standard made the PlayStation 3 a capable all-round media center.
Coupled with the prominence of Sony's sub-driven music and video streaming services, the change of direction had a cynical sheen.
And gameplay uploads won't be sent straight to YouTube or a nearby PC for editing, with only Facebook, UStream and TwitchTV in the wheelhouse. Budding live streamers can't quite rub shoulders with YouTube stars like PewPieDie or Total Biscuit.
But does Sony have any other options?
The MP3 standard, popularized in the mid-90s, is subject to licensing fees and has been superseded by a slew of alternative audio codecs since: Apple's preferred AAC, audiophile favorite FLAC, even Sony's own ATRAC.
Meanwhile, Sony executives will not have forgotten the hacking scandals that threatened to engulf the PS3, nor the losing battle over PSP security.
An unfettered PS4 might spell file-sharing convenience for consumers, but could crater the machine's viability for professional creatives, dooming the device; limiting the mobility of music and video prevents that, at least in theory.
So "thanks for the feedback to the lack of MP3 and DLNA support at the launch of PS4," was the diplomatic response from Sony Worldwide Studios head Shuhei Yoshida. "I'll share with the PS4 Dev team for future consideration.... we're happy & appreciative to learn so many people use and like PS3's media features."
And if the PlayStation 4 remains the enthusiast's preference in comparison to the Xbox One and its stormy pre-launch run, the Nintendo Wii U could yet benefit from any resulting fallout.
Weaker than its competitors, yes, but cheaper too, the Wii U has had a year on the market and an established library of games, while Sony and Microsoft are fully occupied with potentially difficult launches this holiday season.
